研究目的:

本研究旨在通过基于行为改变轮理论(Behavior Change Wheel,BCW)与家庭健康理论指导的移动健康干预,评估其对产前筛查高风险孕妇产前诊断率以及妊娠结局的影响。具体目标是了解该人群对产前诊断的现有认知和意愿水平,基于行为改变轮理论的能力、机会和动机三大要素和家庭健康理论的家庭健康因素,设计个性化的健康教育干预方案,并通过微信平台进行干预。研究将通过随机对照试验(RCT)评估干预效果,分析干预中哪些行为改变因素对产前诊断意愿的提升起到了关键作用,最后,研究还将通过追踪妊娠期健康数据,评估干预对妊娠结局的影响,特别是在减少早产、低体重儿等不良妊娠结局方面的效果。通过以上分析,本研究旨在为移动健康干预在遗传病筛查中的应用提供科学依据和可推广的干预模式,推动产前诊断与出生缺陷防控工作的进一步发展。  

Objectives of Study:

This study aims to evaluate the impact of mobile health intervention based on behavior change wheel (BCW) theory and family health theory on prenatal diagnosis rate and pregnancy outcome of high-risk pregnant women in prenatal screening. The specific goal is to understand the current level of cognition and willingness of this population to prenatal diagnosis, design personalized health education intervention program based on the three elements of ability, opportunity and motivation of behavior change wheel theory and family health factors of family health theory, and intervene through wechat platform. The study will evaluate the intervention effect through randomized controlled trials (RCTs), and analyze which behavior change factors in the intervention play a key role in improving the willingness of prenatal diagnosis. Finally, the study will also evaluate the impact of the intervention on pregnancy outcomes, especially in reducing adverse pregnancy outcomes such as premature birth and low birth weight infants, by tracking pregnancy health data. Through the above analysis, this study aims to provide a scientific basis and a scalable intervention model for the application of mobile health intervention in genetic disease screening, and promote the further development of prenatal diagnosis and birth defect prevention and control.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用Excel软件生成随机数列。首先在Excel中新建工作表,A列输入编号(1至N),B列输入公式“=RAND()”并填充至N行,生成0到1之间的随机数。然后将B列随机数复制并粘贴为“值”,以固定随机数。最后按随机数排序,根据排序后的编号顺序将研究对象分配到不同组别,确保分组的随机性。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study used Excel software to generate random sequences. First, create a new worksheet in Excel. In column A, enter the number (1 to N), and in column B, enter the formula "=RAND()" and fill in N rows to generate a random number between 0 and 1. Then copy and paste the random number in column B as a 'value' to fix the random number. Finally, sort by random number and assign the research subjects to different groups based on the sorted numbering order to ensure the randomness of the groups.

本研究数据采集主要通过电子调查问卷完成,问卷设计采用标准化格式,确保数据的准确性和完整性。少部分指标如病历信息等通过医院信息系统导出,导出数据经严格核对后纳入数据库。数据管理采用双人双录入方式,录入后进行逻辑核查和一致性检验,确保数据无误。所有数据存储于加密服务器,定期备份,访问权限严格限制,保障数据安全。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The data collection for this study was mainly completed through electronic survey questionnaires, which were designed in a standardized format to ensure the accuracy and completeness of the data. A small portion of indicators such as medical record information are exported through the hospital information system, and the exported data is strictly verified before being included in the database. The data management adopts a dual person and dual input method, and after input, logical verification and consistency check are carried out to ensure the accuracy of the data. All data is stored on encrypted servers, backed up regularly, with strict access restrictions to ensure data security.
